Suisei had been excited about her newest solo concert for months. Her dream had always been to be an idol and as a result she had always loved performing live for her fans. While the concerts weren't quite the real deal - it was still an avatar, after all - they were the closest thing that she could get. Live singing was of course what made it fantastic, but the motion tracking from the suit that she'd be wearing would mean that the dancing would be live as well.
She'd practiced with her usual dedication, of course. Her singing had improved dramatically since she'd joined hololive, but her dancing still could use some work, so she'd put in the time. Four hours every day, first to get the moves down and then to sing while moving, timing her words to the beat to ensure that she'd be able to do it when the day finally came. It was exhausting and it was challenging, but it was also exhilarating. She would be a real idol!
Then the text came. "I'll be sending you a package. Be sure to wear it for your live show." Suisei knew who it was from and knew that she couldn't disobey, but part of her was nervous. What was it that her Master would make her wear? Some sort of lewd lingerie? The fans wouldn't see it, but the staff at Cover would. This could ruin her reputation! Another message came. "You can wear it under your outfit." It set her at ease. Maybe things would be okay. She could still put on her show, and satisfy her Master's request while still remaining a pure idol in the eyes of her fans and her company.
Then the package came.
It was inconspicuous at first. Just a set of underwear, really. A modest pair, when you came to think about it. Very solid material. Uncomfortable, but not to the point that it would actually chafe. Once she'd put it on, though, and felt the protrusions positions over her clit and the entrance to her sex, she knew that things wouldn't be so easy. 'Is it really worth it?' she thought, and slipped her fingers into the bands around her waist. 'Can't I just disobey this one time?' Then there was a click. The waistband tightened, becoming almost painfully taut around her fingers and forcing her to pull them out. Once she did, there was no going back in. The belt was locked in place, and this strange pair of underwear, which completely covered her pussy and ass, couldn't be removed. "Chastity?" She mused, trying to tug on the sides. "I can deal with chastity." She flipped her hair over her shoulder and finished getting dressed.

When she started her show, she could almost forget that she was wearing the special device that her Master had sent. It was tight and it was rough, but it wasn't unreasonable. She could still move and she could still sing. It all seemed like it would be going okay when the first thrum went through it.
The sudden sensation pulsed against her clit and between her lower lips, buzzing with an intense energy. Her words caught her throat, the song not coming out, and she tensed, leaning forwards at the sudden burst of pleasure. 'What is this?' she thought, taking a quick gasp as she tried to regain control. 'Is this the -' Another pulse came through, and she dropped to her knees, twitching, as pleasure erupted through her body.
"No." She said it out loud. She Would finish her show! She forced herself to stand, her legs trembling, and continued to sing, picking up where the song had left off. The vibrators thrummed again, choking her words. How could she sing like this? How could any woman resist this pleasure? She let out a squeak, a sharp high note in comparison to the beautiful low voice that she had been employing, and pressed a hand against her crotch. She gripped at the chastity device, trying to stop it from pulsing against her most sensitive recesses, but couldn't do anything to stop the pleasure. After several long, almost agonizing seconds, it paused. She gasped, coughed, then gasped again and tried to continue. She would make it through this. Somehow, she just had to.
The vibrator was obviously remote controlled. She had no way of removing it, no way of stopping it, and no way of stopping herself from collapsing with pleasure each time it buzzed inside of her body. After an hour of its inconsistent pulses, teasing her to the point of aching and always thrumming just as she needed to concentrate most, she knew that her concert had been ruined. Tears filled her eyes, but for all of her frustration she was hopelessly aroused. Her nipples were fully erect at the apex of her firm little breasts and her tights were soaked with the liquid proof of her body's betrayal. She had to try - she didn't know any other way to live other than to try her best - but she already knew that she would fail.
She moaned aloud through one song, dropped to the floor gasping at the climax of another, but was never allowed to climax herself. Her body was aching, her legs were trembling, and drool dribbled from a corner of her mouth, but she was never allowed to cum.
